custom link shortcode not working

As per this article I have set up a custom link as indicated:

function mailpoet_custom_shortcode_referral_link($shortcode, $newsletter, $subscriber, $queue, $arguments) {
  // always return the shortcode if it doesn't match your own!
  if ($shortcode !== '[link:cj]') return $shortcode;
	
  $referral_link = get_page_link(get_page_by_title('curated journeys live feed')->ID) . '?email=xxxx';
  
  return $referral_link;
}

On a test page the set value

get_page_link(get_page_by_title(‘curated journeys live feed’)->ID) . ‘?email=xxxx’

is correct. It shows the value

https://example.com/6ge628fd7e/?email=xxxx

But the email itself includes a link like this:

https://example.com/?mailpoet_router&endpoint=track&action=click&data=WzI2LCIyNzVjYzciLCI0IiwiM2RkMjNiNGQ1ODg0IixmYWxzZV0

ie there are two problems:

(1) the part of the url after the domain name

6ge628fd7e/

has been dropped
(2) the get data

?email=xxxx

has been replaced by tracking data

What am I doing wrong?
